In today's increasingly data-intensive academic environment, data is becoming the foundation of academic communication as a research outcome rather than a research by-product. However, there is a limit to guaranteeing actual data reuse only by expanding the data supply or securing accessibility. In order to overcome this, it is necessary to understand the data reuse behavior and data needs in-depth. Therefore, this study attempted to identify the major data reuse behavior and data needs among researchers. To this end, the authors of KCI papers among the data reuse documents of the Korea Social Science Data Archive (KOSSDA) for the past 3 years were targeted. An in-depth interview was conducted with 12 researchers who accepted the interview. As a result, factors considered when reusing data were personal, economic, technical, and social aspects, and it was found that the data itself was used or contextual information of the data was used depending on the purpose of data reuse. The path to acquiring data is a web-based source of information, and a path through informal communication can also be found. In terms of the data needs, it was found that they prefer English, the United States, and institutional producers. Also they have a clear preference for quantitative data from an interviewer-filled interpersonal interview survey method, rich metadata along with raw data, and data that contains identification information. However, due to the lack of confidence in the value, it is negative for the use of data with controlled access and use, and it is difficult to confirm a clear preference because there is no similar data available for selection in terms of size and freshness.

In this study, a mixed research method that collects and analyzes qualitative and quantitative data together was used to broaden the understanding of young children's faith. First of all, the contents of interviews with 18 research participants were divided into categories, and the frequency of each category was calculated. From 75 statements made in the interview, the importance of each was evaluated with a 5-point Likert scale. The means and standard deviations of the evaluation score were calculated, and sub-factors were identified through exploratory factor analysis. The frequency of categories mentioned in the qualitative interview was in the following order: faith manifested in difficulties, religious activities, Christian education at home, Christian education in the church, love and faith in God, and the formation of a Christian worldview (identity). The statement on the perception of God, theological concepts, religious activities, and Christian education at home and in the church received high scores. On the other hand, statements on developmentally difficult or abstract content, value judgment or conflict resolution based on the Word, and evangelism showed low scores. The sub-factors extracted through factor analysis were faith education through home and church, awareness of God and religious activities, identity based on the gospel, character based on the gospel, and overcoming a crisis through faith. In conclusion, the results of each of the mixed methods of looking at young children's faith were very similar-relationships with God, religious activities, Christian worldview (identity), Christian education at home and church were highlighted, even though various methods were used. This study is meaningful in that it suggests what and how to teach in early childhood Christian education.

API call sequence analysis is a kind of analysis using API call information extracted in target program. Compared to other techniques, this is advantageous as it can characterize the behavior of the target. However, existing API call sequence analysis has an issue of identifying same characteristics to different function during the analysis. To resolve the identification issue and improve performance of analysis, this study includes the method of API abstraction technique in addition to existing analysis. From there on, similarity between target programs is computed and clustered into similar types by applying LSH to abstracted API call sequence from analyzed target. Thus, this study can attribute in improving the accuracy of the malware analysis based on discovered information on the types of malware identified.

Recently, the health-pleasure trend, which means enjoying health care through exercise or diet and certifying it on SNS is spreading to the MZ generation. This study examined the effect of personality traits on SNS upload behavior and subjective well-being related to health care. As a result, 1) parallel comparison and narcissism had a positive effect on the SNS upload attitude and intention, and the downward comparison had a negative effect on both SNS upload variable. Self-esteem had a positive effect only on the attitude of uploading SNS. Next, 2) self-esteem had a positive effect on both subjective well-being, while narcissism had a negative effect on stress, and parallel comparisons had a positive effect on life satisfaction. In other words, it was confirmed that comparisons with similar people had a positive effect on SNS upload behavior and their subjective well-being, while health care for self-show or recognition of others had a negative effect on their subjective well-being. The results of this study should be actively reflected not only for the marketing market but also for a media and cultural environment in which the MZ generation can lead a healthy life.

본 논문에서는 PKI의 보급으로 변화 될 미래(가까운) 인터넷에서 개인의 프라이버시 침해와 관련하여, 고민해야 할 선택의 문제를 제시한다. 우리는 앞으로 규제되고 통제된 인터넷 공간에서 활동할 것이다. 그런데, 현실 공간과 사이버 공간에서의 가치충돌로 인해 발생할 당면 문제에 대해 우리는 문제 해결을 위해 현상을 해석하고, 여러 가지 해결 방안 중 사이버공간에 맞는 올바른 해석을 선택 해야한다. 한 예로 사이버 공간에서 행해지는 진보된 새로운 기술을 가진 감시자의 행위가 판단자(현실공간에서 삶을 영위하는 사람들)로 하여금 개인의 프라이버시 침해인 것인가에 대한 판단을 요구 할 것이다. 선택의 결과는 많은 논란과 여러 가지 해석의 차이를 불러일으킬 것이며, 그른 해석과 선택으로 인한 개인의 프라이버시 침해는 전혀 예기치 않은 곳에서 발생 할 것이다. 사이버 공간은 현실 공간과 유사하지만 전혀 다른 공간이다. 이에 따라 관련 법규의 해석과 적용 역시 현실 공간과 다르다. 이의 관점에서 현재 우리나라의 전자서명 및 전자거래 관련 법규와 PKI 구조에서 이에 따른 해석의 모델을 제시하고자 한다.

3 차원 공간상에서의 상호작용이란 특정 공간내의 오브젝트를 그 위치와 좌표축에 따라 조작하는 행위를 말한다. 이러한 3 차원 공간상의 상호작용을 행할 때 발생하는 가장 큰 문제중의 하나는 사용자가 현재 조작하고 있는 커서 또는 포인터의 깊이적 위치를 알기 힘들다는 점이며 흔히 깊이 지각문제(Depth Perception Problem)으로 불리 운다. 본 논문은 깊이 지각문제를 발생시키는 기본적인 요소중의 하나를 가상환경을 표현하기 위해 인공적으로 생성된 조망 절두체라고 고려하고 이에 대해서 논의한다. 이를 위하여 3 차원 입력 장치(SensAble PHANToM(R) OmniTM)를 이용한 간단한 위치지정 작업을 다양한 FOV(Field of View)와 VD(Viewing Direction)의 환경에서 피실험자들에게 수행하게 하였다. 결과적으로, 작업환경내의 FOV 변화는 작업수행의 정확도에 영향을 끼쳤으며, VD 의 경우, 사용자가 실제로 작업환경을 보는 것과 유사한 VD 환경이 효율성의 측면에서 보다 더 높은 작업수행 결과를 보였다.

수의사의 의사결정 과정에는 모든 의료행위에 내재된 본질적인 특성인 불확실성 (uncertainty)이라는 문제가 필연적으로 개입되는데 특히 진단검사와 관련된 신뢰도와 정확도 측면에서는 더욱 그러하다. 기존의 진단방법에 대체할만한 새로운 검사법이 개발되었을 때 실제로 이를 임상적 진단에 활용하기 위해서는 이 검사의 민감도와 특이도를 추정하는 작업은 필수적이다. 예컨대 표준검사법 (gold standard)이 제시되어 잇을 경우 비교적 간단한 계산으로 추정이 가능하지만 대부분의 질병에서와 같이 표준검사법이 없을 경우에는 상당한 통계적 지식을 요구한다. 또한 소위 표준검사법이라고 하는 검사도 실제로 질병에 이환된 집단과 이환되지 않은 집단을 완벽히 이분해주는 (dichotomize) 능력을 가진 것이라고는 볼 수 없기 때문에 추정과정에 신중을 기해야 한다. 본 원고에서는 다양한 상황에서의 진단검사의 민감도와 특이도를 추정하는 방법에 대하여 기술하며 본 원고에서 설명한 내용과 유사한 자료에 대하여 분석을 원하는 독자는 저자에게 연락을 주면 자세한 분석절차에 대하여 논의가 가능하다.
